Chlorination Certificate Most new service pipe connections to water company mains require a chlorination certificate and UKAS laboratory testing before the connection is made. Requirements vary for different water companies but for most, pipes over a certain size/length (or potentially contaminated) must be chlorinated. Chlorination is also required for conversion from a private water supply to mains water.
Chlorination is often a contract requirement for the commissioning/handover process for new buildings (commercial & domestic) where new pipes, plumbing, tanks and fittings have been installed.
Chlorination normally takes place a week before the connection is due to be made. Pipe work must be installed and protected in accordance to hygienic practices with open ends securely protected using mechanical compression fittings.
We chlorinate in compliance to the British Standards; BS 6700, BS EN 806 or BS 8558.
Our chlorination services are used by leading national & international brands, businesses and organisations.
Why is Chlorination Required? Chlorination ensures that the pipe work is clean and free from contamination. Chlorination is important for new installed pipes/plumbing, existing plumbing or where contamination is suspected. For most sites we offer a free repeat chlorination if the microbiological test fails.
The Chlorination Process Proportional chlorine dosing equipment is used to ensure the exact chlorine residual is achieved. Chlorine levels are electronically measured using a photometer and microbiological samples are tested in an UKAS laboratory. Materials, products and chemicals used are approved for use in contact with drinking water. This includes ultra low bromate sodium hypochlorite.

Chlorination after prolonged period of non-use The HSE document; Legionnaires’ disease Part 2: The control of legionella bacteria in hot and cold water systems details the actions to take when recommissioning plumbing systems taken out-of-use (and not regularly flushed). Paragraph 2.52 on page 24 states that prior to ue the system should be treated as a new installation and cleaned, flushed and disinfected;
As well as commercial buildings, disinfection by chlorination should be considered for domestic/rented properties such as those that have been unoccupied for a prolonged period prior to new owners/tenants. Chlorination services can also be provided for the following;
